Conductometric Level Sensor with Connector DU-003

Conductometric level sensors DU-003 are designed to signal the levels of electrically conductive liquids (water, milk, food products - weakly acidic, alkaline, etc.).

In the simplest form, the conductometric level sensor DU-003 consists of stainless steel electrodes, one of which serves as a common electrode in the control circuit and is installed in the tank so that its working part is constantly in contact with the liquid. In particular, the common electrode can be the conductive body of the tank containing the liquid. The other electrodes perform the signaling function and are located at specified levels to be monitored.

Single-electrode level sensors are suitable for operation in metal tanks of closed or open type.

The conductometric level sensor DU-003 is manufactured with mounting threads: metric according to ISO 724, cylindrical pipe thread BSPP / ISO 228-1 and conical inch thread NPT / ANSI-ASME B1.20.1. The mounting thread can be made to Customer’s requirements according to other standards.

For installation on site, the level sensors are equipped with standard threads M20x1.5, M16x1.5, or G1/2.
Both horizontal and vertical installation of the conductometric level sensor DU-003 with connector is possible.
To extend the working part of the electrodes, the user can use the thread at the end of the electrode.

Conductometric level sensors are made of steel grade 12X18H10T according to EN 10088. Upon Customer request, thermometer sleeves can be manufactured from other steels.
